To calculate terminal velocity, start by multiplying the mass of the object by 2 then, multiply that number by the acceleration of the object due to gravity and write your answer down next, multiply the density of the fluid the object is falling through by the projected area of the object. Purpose to use the labpro, motion detectors, and a laptop computer to produce position vs time and velocity vs time graphs and to analyze them to determine how mass and surface area affects the. The method applies newton's law of motion under force balance on a falling sphere ball when it reaches a terminal velocity in newton's law of motion for a falling ball, there exist buoyancy force, weight force, and drag force, and these three forces reach a net force of zero.
Samples of student report sections one lab partner then (the terminal velocity in m/s factoring in assuming that the velocity consists of two parts, free-. T is the terminal velocity of a spherical particle in a fluidizing medium (3) the exponent, n, the exponent, n, depends on the flow conditions -- that is, on the reynolds number. To best transform the nonlinear relationship to a linear relationship between drag force and terminal velocity we took the natural log of the mass and plotted them with the natural log of the velocityto find the drag coefficient we used the slope and the y intercept that we aquired from the graph and plugged them into the equation : k = 1.
The goal of this lab is to model an object falling with an air resistance force one model that can be used is this says that the air resistance force is proportional to the square of the magnitude of the velocity and a constant c. In this physics lab we'll be studying the phenomenon of terminal velocity using a coffee filter by the end you'll be able to describe the relationship between terminal velocity, mass, and momentum. 10d air resistancervs - 2 - 8/14/2008 a function of the velocity in this case, newton's second law yields a differential equation for the velocity. Since terminal velocity is the maximum velocity, this peak is the terminal velocity of the book after it reached terminal velocity it hit the ground and produced the steep downward slope 4.
Terminal velocity hopefully you won't meet too much resistance while doing this activity drop a single filter from 1 meter and a double filter from 14 m. When an object is falling with a constant velocity, we describe it with the term terminal velocity, or v t the paper reaches terminal velocity very quickly, but on a short drop to the floor, the baseball does not. Similarities to evaluating the terminal velocity of a single particle in a ﬂow here however, the balance must be performed on the entire bed of particles as shown in figure 3. 1 you could use a more sophisticated timing system, but the point here is to demonstrate terminal velocity rather than to make precise measurements 2 advanced level students could determine the viscosity of the liquid, using stokes' law.
In experiment #3, a falling marble was dropped in glycerin and its terminal velocity measured for use in calculating the drag force for experiment #4, a rotational viscometer was used to find glycerin's viscosity at laboratory room temperature. Background information: the amount of air resistance an object encounters is directly proportional to its surface area and velocity terminal velocity, v t, is achieved when the air resistance equals the object's weight and the object can no longer accelerate. 000844-0029 3 of the coffee filter per time interval, and allow us to derive the velocity of the coffee filter we should also be able to find the terminal velocity, which is the true dependent variable for this.
This lab that our entire class have conducted deals with the relationship of an object's physical surface area to time it takes to hit terminal our report terminal_velocity_labpdf. Use the same setup as in previous part of the lab to record the terminal velocity of beads under several different conditions: randomly choose two beads (either steel, aluminum or nylon, either 1/2, 1/8 or 1/16 inch diameter) to be measured in water. By fitting a linear function to this part of the data, i can get the velocity of the filter—which would be the terminal velocity for this particular run you can see the slope is 1730 m/s.

The velocity dependence of the drag force while it is diﬃcult to estimate the mass of a single coﬀee ﬁlter (we will try in part 2), we can be reasonably conﬁdent that 2 coﬀee ﬁlters is twice the mass of 1, 3 coﬀee ﬁlters is 3 times the mass of 1, etc. Having performed this lab, a student suggests that the terminal velocity of a 25-gram penny would be 138 m/s which one of the following statements is incorrectly assumed by the. Millikan oil drop data analysis: reaches its terminal velocity and moves with a constant velocity hence the total force on the oil drop down must be bigger. View lab report - terminal velocity versus mass labrotory design and calculation lab from physics sph4u7 at bayview secondary school purpose: how does terminal velocity of falling coffee filters find study resources.
